UNITED STATES PATENT FEIGE6 WILLIAM B. MCCLURE, OF ALEXANDRIA, VIRGINIA.

IMPROVEMENT IN CART-SADDLES.

Specification forming part of Letters Patent No. 108,614, dated October25, 1870.

To ad whomI it may concern Beit known that I, WILLIAM B. MCCLURE, ofAlexandria, in the county of Alexandria and State of Virginia, haveinvented a new and Improved CartSaddle; and I do hereby declare that thefollowing is a full and exact description oi' the same, reference beinghad to the accompanying drawing, and to the letters of reference markedthereon.

This invention relates to that class of cart saddles which are providedwith rollers, ar` ranged transversely across the groove in which theback-chain lies,for the purpose of easing the movement of the latter asone side ror thevother of the cart may be temporarilyv elevatedordepressed on account of the roughness of the road over which the cart ispass ing, and consists in certain details of construetion, which will befully described hereinafter.

In the drawing, Figure 1 is a plan view ol my invention. Fig. 2 is aside elevation, and Fig. 3 a cross-section.

To enable others skilled in the art to which my invention appertains tomake and use the saine, I will now proceed to describe fully itsconstruction.

A represents a cart-saddle, of any proper construction, which isprovided with the usual groove a for the reception of the baclccliain.

b b b representsolid rollers, which are provided with journals at cachend, as shown. c

c c represent boxes, suitably constructed for the reception of thejournals of the rollers D, which are secured in orifices in the flangesa' of the saddle in any proper nia-nner. I preferably, however, cast aiiange, c', upon the boxes, which is provided with screwholes, by meansof which it is secured to the saddle by screws, as is clearly shown inthe drawing.

The advantages of this construction are as follows: The amount offriction incidental to the revolution of thc rollers is much reducedover the ordinary forms of construction, inasmuch as the rollers restonly on the bearings in the boxes. The boxes may be inserted in theflanges of the saddle without danger of splitting the wood 5 and thewhole may be constructed at a cost little above that of the ordinarysaddle.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The cart-saddle A, with groove a, ilanges a', rollers b, and boxes c,when the parts are combined and arranged as described, for the purposeset forth.

This specification signed and witnessed this 5th day of September, 1870.
